The Kasparov/Vaganian Gambit The introductory position of the <Kasparov/Vaganian Gambit> can occur after 1 d4,1 Nf3 and 1 c4, which can appeal to a wide range of players. The usual move order is <1 d4 Nf6 2 c4 c5 3 Nf3 cxd4 4 Nxd4 e5!? 5 Nb5 d5 6 cxd5 Bc5> bringing us to a very sharp position.

9.N1c3 (this is fine for Black, but I'm not sure that White has any route to the advantage: 9.Qd5 Bb4+ 10.Bd2 Nxd2 11.Nxd2 a6 is fine for Black too, since 12.Nc7 can simply be met by 12...Ra7 ,; and 9.Qc2 Bb4+ 10.Bd2 Nxd2 11.Nxd2 a6! is also at least equal for the second player, because 12.Nc7?! Qxd6! 13.Nxa8? Bf5 14.Qd1 Rd8 regains a piece with a crushing initiative)

9...Nxd6 10.Qd5 (otherwise Black has managed to regain his pawn with equality)

10...Na6 11.Qxe5 Re8 12.Qh5!?

(12.Qd5 Be6 13.Qd1 is somewhat more sensible, although I still rather like Black's lead in development after 13...Qe7)
